I was told by someone in the industry that I trust, Maestro is just a cryo’d hospital grade outlet.
No green dot.... For the receptacle to be a hospital grade outlet it would have to have the green dot.
Looking at the picture of the Maestro outlet compared to the Cooper BR20 Commercial grade outlet they are identical. Right down to the Trade Mark found around the wall plate mounting support screw hole.
